LOGAN, Utah - It was a dark
day for CubeSat builders. The seventh launch of the Dnepr launch vehicle hauling over
a dozen spacecraft blasted upward into the night from its silo site at the
Baikonur Cosmodrome, Kazakhstan.

But
some 73 seconds after launch, the converted Cold War SS-18 missile ran into
trouble. The booster and its cargo of satellites crashed down range, plowing
into an unpopulated desert area.

The accident meant the loss of 18 satellites, including the first spacecraft of Belarus--a remote sensing craft called BelKA--along with a Russian Baumanets satellite developed by the students of Bauman State Technical University. Also onboard, several smaller satellites: UniSat-4 and PiCPoT from Italy, and five "P-Pod" containers collectively loaded with 14 CubeSat satellites from 10 different universities around the globe and the U.S.-based The Aerospace Corporation, a private company.

It was billed as the largest deployment into Earth orbit of CubeSats ever--a milestone that was not to be.

There was a sense of shared loss and requisite group therapy--as well as passion to move forward--within the CubeSat community that gathered at the 20th annual conference on small satellites, held here at Utah State University earlier this month.

Stolen success

In
an update on the Dnepr failure from ISC Kosmotras, the Russian and Ukrainian
rocket-for-hire group, a malfunctioning hydraulic drive unit of a combustion chamber
on the booster's first stage has been branded as the root cause of the July 26
crash.

Watching
the launch a few miles away at Baikonur was Dave Klumpar, research professor of
physics at Montana State University and head of the school's Space Science and Engineering Laboratory. The Dnepr carried the school's
first-ever satellite, the Montana EaRth Orbiting Pico Explorer, or MEROPE for
short. It was a proud product of some 5 years of work.

"We
watched the rocket arc overhead...then there was a bit of a flash and
darkness...followed by a couple of dimmer flashes. That was our first clue that
there might be something wrong," Klumpar recalled. "At first there was a lot of
uncertainty, followed by total letdown."

"We
were really looking for a success...to show we built a successful satellite and
it operated in the space environment," Klumpar said. "And that was stolen from
us. We can't make that claim."

Educational punch

While
CubeSats may be petite in size, they pack an educational punch.

CubeSats measure about four
inches--just 10 centimeters--in size and weigh a mere 2.2 pounds (one kilogram).
Their standardized shape makes them cheaper to produce in a much shorter period
of time, with students able to design, build, test, launch and operate the
satellites while still in school.

The
CubeSat Project is an international collaboration of over 80 universities, high
schools and private firms busily building the diminutive devices. The tiny,
hold-in-the-palm-of-your-hand satellite is built to specifications developed by California Polytechnic State University in San Luis Obispo, California and Stanford University's Space Systems
Development Laboratory.

Through companies like
Kosmotras, CubeSat launch costs currently translate to about $40,000 per single
cube for the developer.

CubeSats
can perform many tasks. Several duties of the recently destroyed satellites,
for example, were to flight qualify a wide variety of small sensors and
attitude control devices; take images of Earth; collect data on the electrical
strength of clouds in the ionosphere; as well as chart the Van Allen radiation
belts and test hardware and ideas not yet flown before in space.

Eye-opening experience

"The
Dnepr failure was really hard for a while," said Cal Poly's Jordi Puig-Suari,
CubeSat Project Co-Director and chair of the university's Aerospace Engineering
Department. "I probably didn't realize how hard it hit us. For two weeks we
didn't get too much done. Everybody was in a zombie state," he told SPACE.com.

Puig-Suari
said that CubeSat teams worked long and hard in readying their respective
satellites for launch on the Dnepr. "It was a positive step that we made it to
the rocket...not a trivial thing. It was a kind of eye-opening experience and as
real-world as it gets."

Added
William Whalen, a Cal Poly aerospace engineer specializing in thermal vacuum
testing of CubeSats: "It was devastating, obviously, immediately after the
failure." Still, numbers of universities are working on follow-on CubeSats, he
said.

"We're
not stopping...we're looking for more launch opportunities. We're not going away.
This work will continue to continue...and expand," Whalen said. "If you want to
play with the big boys, this is our chance. It isn't just to go up there and
show that we work, but it's also to show that we're resilient."

Mindset is changing

As for
the future of CubeSats, Puig-Suari is taking the small is beautiful route.

"I
think we're starting to get interesting. The technology is shrinking and we can
do useful things," Puig-Suari said, thanks to micro-electronics, powerful
processors, tiny cameras and other systems.

"There
was a lot of skepticism on the part of industry," Puig-Suari said, "that
CubeSats couldn't really do anything useful because of size."

That
mindset is changing, Puig-Suari added, with CubeSat developers now working on
attitude determination, control and pointing accuracy--features that can lead to
an array of future applications.

"Things
are picking up," Puig-Suari suggested. "We're starting to see industry CubeSats
that are not from universities. NASA is building them; Boeing and The Aerospace
Corporation too. That's very different from the past. That kind of shows that
there's something here that wasn't here before."

Building an infrastructure

The
momentum behind CubeSats won't be shoved off course by an errant booster, said Bob Twiggs, CubeSat
Project Co-Director in the Department of Aeronautics & Astronautics at Stanford University, California.

"We
have always said that getting the student satellites to the launch completes 95
percent of the educational goals of the project," Twiggs advised. "There is
disappointment for everyone, but they can also be proud of the achievements
made in their program. There are many levels of success that we try to
stress in the student satellite programs like building an infrastructure at the
schools that allow them to do such projects. They learn many skills that
we can't teach in the class room."

Despite the launch snag, Twiggs said, the CubeSat student efforts are
developing the best trained students that will be the next generation of space
engineers..."and we hope a much larger generation of the general public that has
a renewed interest in space exploration."
